Author/Opus: This is the 219th puzzle from our contributing puzzlemaster Grant Fikes.
Rules: Combination of Pentominous and Star Battle. Place stars into some cells so that there are two stars in each row and column; no two stars can touch, even diagonally. Then divide the rest of the grid into 16 regions each containing 5 cells. Regions with the same shape (including rotations/reflections) cannot share an edge. A cell with a letter in it must be part of the pentomino shape normally associated with that letter; an inventory of pentominoes is given below the puzzle.
Answer String: Enter the letter associated with the pentomino occupying each cell or an asterisk (*) if it is a star in the marked rows from left to right, separating the groups with a comma. Use CAPITAL LETTERS! Example: IIIII*LFF*,TTT*PP*VVV
